To all whom it may'concern:

Be it known that I, HANS STAROKE, a citizen of the German Empire,residing at Elberfeld, Germany, have invented certain new and usefulApparatus for Use'in Recording Telephonic Messages or Sounds, of whichthe following is a specification.

- In apparatus hitherto known for recording telephonic messages orsounds on a phonegraph-cylinder without anp assistance of the s eakerthe recordingwas imited to a single rum, so that onl a limited amount ofconversation could e recorded in this 'way. This drawback is obviated bythe resent invention by a series of phone up -cylinders beingsuccessively brought into the desired recording position by an automaticapparatus, hereinafter described, the beginand the end of the throwinginto gear of e cylinders being notified to the users by the ringing of abell in roximity to the mouthpiece or diaphragm o the receiver so thatthe conversation may be recorded with- V out anygaps. 3s

A construction ofthe apparatus according to this invention isillustrated, bg rway ofxs ample, in the accompanying swings, in whichFigure 1 is a longitudinal section through a switching apparatusaccording to this Invention. tion on the line A A seen in thedire'ctionof the arrow. Fig. 4 shows the connectiondiagram Fig. 5 thearra ement'ofcha e-' wheels. Fi .6 shows the r atchet-g-ear cit 's anism for stoppingthe changing ofthe cy1in ders; and Figs. 7 and 8" are top ian views ofFigs. 7 and 8, traites the signaling the change.

he arrangement and the working of the ap aratus are as follows: 7 r

en the a paratus is to be used, eiectro magnets c an d are connectedto'the telegpsone-Iine b by means of switches a. The t electromagnetoperatesin the veil-known manner the needle e, recording theconversation on the cylinder, the second magnet attracting, when currentasses through it,

alover-armature g, PI'OVIdBd with ratchet-- teeth and piyoted atf Fig.6, thus releasing a pawl 11, secured to t e carriage it. When thecircuit is broken, the ratchetteeth under the influence of a s ring 7ccome again into thp path of the paw 'i, so that if the carriage moves inthe direction ofthe arrow c, Fig. 2-

2 is a P g 3, a cross-m igs. 7 and 8 illustrate the mechectively; ig; 9*iiinss of the current. The movement of the carriage is eflected by meansto be hereinafter described:

A toothed'wheel m, Fig. 1, mounted on a spindle Z, is rotated by aclockwork (not s own in the drawings) and transmits its rotation in "theosition shown in Fig. 1 by rneansof whee s n, and o to a screw-spindle3), serving to drive the carriage h that is,'to advancethe carriage inthe direction of the arrow c. When the carriage h nears the end of itstrevei, the proj eetion q upon it strikes a for-kt, pi ed etc, which, bymeans of a fixed iectionu causes the spindle Z to "will be seen from thedirections shown by ar. 5, the spindle p wiii be caused to rows in Firotat'in t e o'p osite direction, effect return 0 the carriage in thedirection 'oithe arrow 1. At the end of the return movement a perfectlysimilar device g s t a miigagaineh'an e the direction of rotation ofmunicated b the wheel m to the spindle Z is "liheispindlep. The rotarymovement comtransmitted y toothed wheels 1 and 2 to a y spifidie 3,carrying the phoncigaph-cylinder,

"winch is caused to rotate. t e cylinder: supporting frame 4 5 issupported by the carriage h, to c move longitu the transmission wheel 1.wheel 1 is mounted on thespindlel by means of ajeather-key sliding inthe groove 6, the shifting during the advance being efieeted by a 8 ring.7,s'ecured to the carria e h, :whiie Whoa I. During that change thepart u linders not only rotate, but] ally also at the same time,"

v hichnioveinents nust also be foigosegity To that end the .roodurlngtire return the driving is e ected by a strikes the toothed wheel1 and by overcoming stee in 7 shifts the latter, thus disengaging'it'iroin the wheel 2. The shifting of the indie Zreleases also for amoment a disk forming the support for the cylinders and arranged on thecross-wail of the carriage, as will be understood on examining I 55number of projections Figs. '7 and 8. During the advance of the carriagethe art 10, mounted on the spindle l, is

in the pat h of the disk 9, so that the latter is thereby prevented fromrotating. On the 5 above-described movement of the spindle l the lockinof the disk is released, so that the --disk can eely move longitudinallyand is locked a ain on reaching the part 12. The release of the disk 9and of the toothed wheel 2 enables the cylinder-sup be turned in thesupport 5 means of an automatically-windin steel and 13. When the nextcylinder as been brought in this way into position, the spindle 3 of theroller 15. is again arrested by the disk 9, as in the meantime the part12 has come into the path of the said disk, and thus revents it fromrotating further. During t e return of the carriage h the toothed wheel1 after the removal of the part it and under the action of the spring 7is immediately caused to en age with the wheel 2, mounted on the spind eof the cylinder. B means of a pawl-gear 21, mounted on the ame andclearly shown in 2 5 Fig.2, the steel band 13 is prevented from becomingunwound, so that, the disk 9 forming an abutment .against which thespindle 3 is held, the phonogra h-cylinder is su ported in asufiiciently ri i manner. On t e shift- 0 ing of the spindle%, whichtakes lace at the end of the return movement of t e carriage, the disk 9must remain locked on the portion 11, so that another change of cylindermay not take place. To this end a second ratchetgear 15, pivoted at 14to the 1011 itudinal wall of the carriage, is provide which ratchet-gearis released dur' the advance of the carriage, as shown in ig. 7. On themovement of the spindle taking place at the 0 end of the advancemovement as soon as the part 12 comes into the path of the disk 9 theratchet-gear 15 is turned, b means of the part 10 and an arm 16, into te lockin position. (Shown in Fig.8.) On the bac ward shifting of thespindle the release of this lookortihg frame 4 to ingear is effected bythe part, 12, which acts on t e pivoted arm 17 assoon as the part 10 hasagain come into the path of the disk 9.

The beginnin and the end of the change are notified to t e speaker by abell operated by pins 18 19, mounted on the carriage h,

w ich strike the lever 2001 the bell-hammer,

which is thus oscillated, the lpins striking the tooth-shapedprojections oft elever20. The

encountered by the pins 18 or 19 and the number of the strokes of thebell caused thereby can be used for distinguishin the beginning and theend of the change 0 cylinders.

The sounds of the bell, amplified, if desired, by a sound-board, areprojected from as near as possible onto the diaphragm of the receiverand thence conveyed through the telephone-line in the well-known mannerto the ear of the person at the transmitter.
